How should I best position my speakers in a home theater system?

It is generally recommended to place them with at least 30cm distance from the back and side walls. Ideally, the listener should also be seated with some distance from the rear wall. Precise spatial imaging is achieved when you position your front speakers in the so-called "stereo triangle." The surround speakers should ideally be located behind the listener at an equal distance from the listening position. Placement recommendations can also be found in your speaker's user manual.
